Step-by-step explanation:
The variable t represents the amount of gas in mom's truck. Since we need to find a number that is 50% more than 12, we use 1.5 (we would use 2 if we want 100% more, so it makes sense that we use 1.5, since we want to add 1/2 of 12 to 12. The answer is 18.)

Answer
27 days
Step-by-step explanation:
father= 45 days
oldest son + father=27 days
youngest + father= 36 days
45-27=18
45-36=9
18+9=27
so it would take 27 days for both sons to complete the house
18 days=oldest son
9 days =youngest son
